Figure 1.
Relationship between diet, the gut microbiota and IBD. Evidence for these relationships is shown adjacent to the solid arrows. Dietary interventions for the treatment of Crohn's Disease are shown adjacent to the dashed arrows - Exclusive Enteral Nutrition (EEN), Restriction Diet (RD), Bowel Rest (NPO) - Further investigation is needed to determine whether or not any observed efficacy from these interventions involves diet-induced alterations in the gut microbiota. GWAS, genome-wide association studies.
